SULKY-PLOW.

SPECIFICATION forming part of Letters Patent No. 226,027, dated March 30, 1880.

Application filed J une 17, 1878- To all whom it may concern:

Be it known that I, BYRON C. BRADLEY, ot' Chicago, Cook county, State of Illinois, have invented a new and useful Improvement in Sulky-Ilows, of which the following is a i'nll description, reference being had to the accompanying drawings, in which- Figure l is a plan; Fig. a rear elevation of the parts shown, with a detail showing the inside ot' the lever, Fig. 3, a side elevation with one wheel removed; Figs. 4 and 5, details of the colter; Fig. 6, an outside view ot one of the plates or blocks by means of which the colter is connected with the colter-standard; Fig. 7, a front view of such blocks; Fig. 8, a top view of the same; Fig. 9, an inside view ot' one of such blocks; Fig. 10g a vertical section, showing the devices for securing the colter-blade in the arms 5 Figs. ll and 12, details. Figs. 6 to l2, inclusive, are enlarged. There are three sheets of drawings.

lWIy invention consists in so constructing the pole-bracket that it can be changed from the outside to the inside of the arm to which it is secured. v

In the drawings, AA are the wheels. B is an iron bar, the ends of which are turned down,forming arms C, in the ends of which the crank is located. One of these arms C is shown in Fig. 3. The bar B and said arms, in fact, form the main frame.

D is a crank. One end of this crank is provided with a spindle to receive the wheel A. The other end has no spindle, the land-wheel A being located on a short spindle which can be raised and lowered.

E is the plow-beam, hinged to the crank D g F, seat; G, foot-rest, supported on the lower end of a bar, a, which bar is secured to the bar B. b is a socket secured to the lower end of the bar ahy means of a iiange and bolt. c is a plunger inserted in said socket b. d is a horizontal rod or bar secured to the lower end of the plunger c. These parts are arranged over the front end of the plow-beam, and so that when the plow is in use the bar d will be in contact with or near to the beam when the plunger is raised, as shown in Fig. 3.

The driver can force the plunger down with his foot, thereby depressing the front end of the beam and raising the heel of the plow, which is desirable when backing.

c is an angle-iron, the two parts being at right angles to each other. It is bolted or otherwise secured to the arm C upon the out side, as shown. The tongue H rests upon and is bolted to the horizontal part of the iron c. This iron e is so made that it can be placed upon the inside instead of on the outside of the arm C, and still receive the tongue. This construction of the pole-bracket e renders it easy to change the pole from one side to the other of the arm C.

I is a lever. Its lower end is secured to the crank D, so that by the use of the lever the swinging portion of the crank can be raised or lowered to regulate the depth ot the plowing.

J is a rack secured to a bar attached to the plow-beam, and f is a sliding bolt so arranged that its lower end can engage with the rack J. It is connected with the leverby means of pins which pass through slots in the lever and one or more suitable guides, or in other suitable manner 5 but it has no spring connected with it to cause it to engage with the rack J.

g is a hook pivoted to the inside of the lever I, arranged to engage with'a pin projecting from the bolt for the purpose of holding it away from the rack. When the bolt is released from this hook it will fall by gravity and engage with the rack. The object ofthe lever is to lock the plow in a fixed position.

It is sometimes desirable to have the plow free to follow and adapt itself to irregularities in the ground. This can be done by raising the bolt and hooking it up.

K is the colter-blade. L are the arms of the yoke. h h are bushings inserted in the boltholes in the arms L, which holes are enlarged. The bushings have a iiange on the outside, and they are tapering at their inner ends, which extend into the hub k, which fits the tapering ends of the bushes, so that the bearing-points are between the tapering bushes and tapering or enlarged portions ot' the interior of the hub, and by tightening the nut t' on the bolt m compensation for wear can be provided for, and the bolt will be protected from wear. This construction also will have the effect of keeping vsand and dirt out of the hub.

IOO

The bushings are prevented from turning in the arms by means of a projection on the bush Iitting into a corresponding recess or slot in the arm, as shown at n', Fig. l0.

The colter-yoke is connected with the standard by means of two blocks, n n, which are provided with ears 0 to receive bolts p. These blocks are recessed longitudinally to receive the standard q, which is round at the lower end, and is provided with a pin, fr, which passes through it. Theblocks n are also provided with transverse recesses s to receive the ends of the pin r, upon which the blocks are supported, and which also limits the lateral movement of the blade K.

What I claim as new is as follows:

The combination of the bar B, having turneddown arms C, the reversible bracket e, andl
